Why Reverse Apodization?

Reverse Apodization maintains continuity of balanced light  distribution and continuous focus regardless of lighting conditions. Patent pending Fourier Optic with Reverse apodization  features  24H Balanced Light Distribution that enables high energy distribution to near and intermediate in mesopic conditions as well as photopic. That unique design promises patients more efficent light distribution and  have clear vision at all distances during daytime and nighttime.

Maximized Light Transmission

ALSAFIT FOURIER provides %91,4 Light Transmission thanks to patent pending Reverse Apodized Fourier Optic . Fourier Optic diffraction on optical area transmit large part of the light to retina by reducing reflected and scattered light. Classical sharp edged and overlapping diffractive IOLs exhibit important light loss(12 to 15 %) which has direct impact on visual performance.

24Hours Balanced Light Distribution

Increasing height of the  Fourier Optic diffraction from central to peripheral on optical area provides high energy delivery  to near and intermediate with the enlarging of the pupil. With 24H Balanced Light Distribution Fourier Optic IOL offers high contrast sensitivity at near, intermediate and far vision and all distances in between during daytime and nighttime.

Our R&D team with its expertize of more than two decades in the IOL industry, considering the history of the hydrophobic IOL materials with their strengths and weaknesses, invested considerable time and efforts to come with a bio-polymer Alsafree combining:

• Glistening-Free
• Designed to minimize PCO
• MICS capable
• Easy handling features

• Alsiol material is a co-polymer made on a methacrylate basis. One of the co-monomer is an hydrophilic monomer (2-Hydroxyethylmethacrylate).
• The second monomer used is a pure hydrophobic monomer (2-ethoxyethylmethacrylate) with large hydrophobic ester chain.
• The benefit of adding this hydrophobic monomer in the formulation is that we confer the polymer as hydrophobic behavior, by reducing the water content.
